Question

Match the expression with its name. 6x4 – 10x + 9 A) not a polynomial B) Cubic binomial C) Fourth -degree trinomial D) quadratic monomial

Answer 1

Fourth - Degree trinomial

Explanation:

`6x^4 - 10x + 9`

It is a polynomial because there is no negative exponent or fractional exponent

We have highest exponent 4. so it is not cubic. For cubic polynomial highest exponent should be 3

Given expression have highest exponent 4 so its fourth degree. We have three terms 6x^4 , -10x and 9. so we say its trinomial.

Hence we name it as Fourth - Degree trinomial

We have 3 terms so this is not a monomial
